The gene for X chromosome-linked severe combined immunodeficiency (SCID), a disease characterized by a block in early T-cell differentiation, has been mapped to the region Xq11-q13 by linkage analysis with restriction fragment length polymorphisms. High logarithm of odds (lod) scores were obtained with the marker 19.2 (DXS3) (z = 5.51 at a recombination fraction theta = 0.11) and with the marker cpX73 (DXS159) that showed complete cosegregation with the disease locus in the informative families analyzed (z = 5.27 at theta = 0.00). Other significant linkages were obtained with several markers from Xq11 to q22. With the help of a recently developed genetic map of the region, it was possible to perform multipoint linkage analysis, and the most likely genetic order is DXS1-(SCID, DXS159)-DXYS1-DXYS12-DXS3, with a maximum multipoint logarithm of odds score of 11.0. Our results demonstrate that the SCID locus (gene symbol IMD4) is not closely linked to the locus of Bruton's agammaglobulinemia (a defect in B-cell maturation). They also provide a way for a better estimation of risk for carrier and antenatal diagnosis.
